METHOD OF MAKING SHINGLE STRIPS.

Original application filed November 12, 1919, Serial No; 337,577.

.1922. Serial at. 593,460.

T 0 all whom it may concern Be it known that I, ALEXANDER S. SPEER, a citizen of'the Unitedstates, residingat Buffalo, in the county of Erie, State of New York, have invented certain new and useful Improvements in Methods of Mak ing Shingle Strips; and I do hereby declare the following to be a full, clear, and exact, description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same.

The invention relates to prepared roofing and particularly to that which is formed in stripshaving notches extending transversely into the strip at intervals along one edge .ofthe same tosimulate the appearance of separate shingles' when .the strips ar'e'laid upon the roof in overlapping relation. The object of the invention is to provide. anew form of shingle strip which affords more complete protection for the roof upon which it is laid and an improved method of making the same involving an economical use of the sheet material from which; the shingle strips are produced.-

In the; accompanying drawings 1 is a plan View showing a plurality of the improved shingle strips laid upon the roof, the relative position of the upper p or covered edge of one of the shingle strips i with respect to the superimposed strips being indicated by dotted lines;

F 'ig. 2 is a' side elevation partly in'section conveniently representing ainachine' which may be used for cutting the improved shingle stn'p from a. web of sheet material;

Fig. 3 is a plan view of the machine illustrated in Fig. 2, and.

Fig. 4 is m detail plan view showing an end portion of the web from which one of the improvedshingle strips has just been cut, the position of the next one being indicated .by a dot and dash line.

Figs. 5 and 6 are plan views of modified .forms of shingle strips or units.

The improved shinglestrip 10 is preferably of sufficient length to comprise a plurality of connected shingle tabs 11, shown as four in number, with intervening slots or gutters 12. These shingle tabs constitute the portion of the strip which is exposed to the-weather, when in use, and a; desirable ornamental appearance and Patent ire/1,412,295, dated April 11,

Divided and this application filed July 14,1920, Serial No. 396,127.- Renewed October S, 1922.

. other advantages areobtained withouoinanywise detracting from the utilityf".of the strip, if each of the shingle tabs. 11 is formed with chamfered corners 13,. Preferably the line of chamfering of the corners 13 extends at any angle of 15 tothe front edge of the strip and reachestohalf the length of the intervening slots or gutters 12.

Under these circumstances the remainder of the strip' 10 may comprise,'without waste of material. a continuous body portion 14.- having the full width usually provided for the portion of a shingle strip which is to be covered by succeeding layers of similar strips. when n use, and a. ser es of extensions 15 arranged along the back or covered edge 16 of the strip in line with the gutters or slots 12. It follows that if each of the extensions 15 conforms in shape;

with the material removed from between the outer end portions of two adjacent shingle tabs 11, a plurality of the shingle strips 10 may be completely formed from a length of web .17 equal only to the combined widths of the strips from the free edges of the shingle .tabs 11 to the rear edge 16- of the main body portion 140i the strip. lVhen this construction is used the only part of the original web 17 which is discarded comprises the short'tongues18 (Fig. 4) removed form the innerend pdrtions of the slots 12 while the full width of the shingle strips '10 from the free edges of the shingle tabs 11 to the rearedge 16 of the main body portion 14 of the strip maybe only two andone-half times the length of the shingle tabs and stillpermit the fulls length of the shingle tabs exposed to the weather and with two full layers of rooting material covering all parts of the roof to the inner ends of the guttersor slots 12. The strips are desirably fastened of the strips being laid upon the roof with are conveniently cut from the web- 17 by means of the machine forming the subject of Patent No. 1,2&9,5-l, granted to A. S;

reference to the rate of feeding of the web 17 that a shingle strip of full width is struck off from the end of the web at each downward movement ofthe knife over the edge of the table. A second knife 28, rotating upon the same axis with the knife 25 and preferably rigidly connected thereto,

' serves to strike off the tongues 18 which would otherwise project from the extensions at the back edge of the shingle strip. As shown, the knife 28 is of such length and is disposed at such an angle with respect to the knife that it cooperates with the table 22 to sheer the web 17 after each operation of the knife 25, as indicated by the dot and dash line 29 (Fig. 4). For this purpose the knife 28 may have a straight edge as in my said former patent; In this case, however,

it'removes onlya part of the material which projects from the end of the web corresponding to the rear edge of the shingle strip after the operation of the knife 25.

It Will be understood that the shingle tabs 11 may have rounded ends. as 30 (Fig. 5) or curved corners as 31 (Fig. 6). Any of these forms may be produced upon the machine illustrated in Fig. 2 if the cooperating cutting edges of the knife 25 and table 22 are made to conform thereto and the material removed from one edge of the strip serves to provide the extensions 33 or 34 at the rear edge of the next succeeding strip without increasing the length of web, as 17, required for the production of the strip.

This application is a division of my copending application, Ser. No. 337,577 filed November 12, 1919, now Patent No. 1,412,- 295, dated April 11, 1922.

I claim 1. The method of producing like multiple shingle strips each having aslotted edge which consists in repeatedly cutting a sheet of the strip material upon broken lines con forming to the outline of the slotted edges of the strips, the said cuts being parallel to each other and separated by distances equal to the width of the strips and between each. two consecutive broken line cuts cutting off a portion only of the fingers left projecting the length of the web, the broken line cuts conforming to the outline of the slotted edges of thestrips and being spaced 1n accordance with the width of the strips and each of the straight line cuts intersecting the fingers left projecting from the end of the web by the last preceding broken line cut.

3. The method ofproducing like multiple shingle strips each having a slotted edge which consists in progressively cutting a web of the strip material at intervals along the same from one end of the web alternately on broken and straight lines transverse to the length of the web, the broken line cuts conforming to the outline of the slotted edges of the strips and being spaced in accordance with the width of the strips and each of the straight line cuts intersecting the fingers left projecting from the end of the web by the last preceding broken line cut intermediate the ends of the said fingers.

4. The method of producing like multiple shingle strips each having a slotted edge which consists in repeatedly cutting a sheet of the strip material upon broken. lines conforming to the outline of the slotted'edges of the strips, the said cuts being parallel to each other and separated by distances equal to the width of the strips and between each two consecutive broken line cuts cutting off the fingers left projecting from the sheet by the last-preceding broken line cut.

5. The method of producing like multiple shingle strips having at one side edge recesses and at the other extensions of less length than the depth of the recesses, with a minimum of waste of material, which consists in progressively cutting a web of material transversely on a line conforming 1e to the contour of t edge having the recesses and with' the extensions on the web, and in afterwards cutting the excess material simultaneously from all of the extensions.

6. The method of cuttinglike shingle strips each having a slotted edge from a length of a web of material which consists in cutting the web at intervals along the same on broken lines transverse to the length of the web and conforming to the outline of the said slotted edges of the strips and removing a part only of each extension left projecting from the web by each of the said broken line cuts,

7. The method of producing like multiple shingle strips having a slotted edge, which comprises repeatedly cutting a sheet of the multiple i memes strip material at intervals along broken lines conforming in outline to the slotted edges of the strips and, following eachbroken line cut, cutting from the sheet the. "material left by-the preceding cut to form the slots in the slotted edge.

8. The method of producing like shingle strips having spaced shingle tabs, the ends of which are .narrower than the width of the body of the tabs, which comprises repeatedly cutting a sheet of the strip material at in tervals along broken lines conforming to the outline of the shingle tabs, and, following each broken line cut, cutting from the sheet the material forming the spaces betweenthe tabs but leaving the material which produces the narrowed ends ofthe tabs.

9. The method-0f producing like shingle strips having a plurality of shingle tabs with narrowed ends, the body of the tabs being separated by slots, each of uniform narrowed ends on the shingle tabs, which and, following each broken line out. severing from the sheet the material forming the slots in the preceding strip but leaving the material forming the widened space between the ends of adjacent tabs.

10. The method of producing shingle strips having aplurality of spaced shingle tabs projecting therefrom, which comprises advancing a sheet of the strip material; cutting the same transversely at intervals, conforming to the depth of the strip, along a broken line conforming to the contour of the edge of the strip having the projecting shingle tabs, and. between each broken'line cut, severing from the sheet the material which is left after the broken line out to form the spaces between the shingle tabs.

11. The method of producing from prepared roofing material shingle units having cut-out portions involving the production of waste, which comprises cutting a sheet of the roofing material at intervals along lines conforming to thecontour of that part of the strip having the cut-out portions but leaving the material constituting the cut-out waste portions attached 'to the sheet of material, and, after each cutting, severing such waste material from the sheet.

12. The method of producing'from prepared roofing material shingle uiiits havin cut-out portions involving the production 0 waste, which comprises cutting a sheet of the roofing material at intervals along lines conforming to the contour of that part of portions of material oqnstituting the waste from the cut-away parts'of the unit attached to the sheet of material, removing the severed unit from the sheet and then 14. The method of producing from pres pared roofing material shingle units having cut-away portions involving the production of waste. which comprises severing said units from said sheet successively along lines conforming to the/contour. of the edge of I severing-the waste. portions from the sheet.- width .but widened at the ends to form thethe unit having the cut-away portions but leaving the waste material forming the cut; away portions'attached to the sheet, said severing being effected by a rotary chopping motion to remove the severed units from the place of severing, and, between each severing of the material, cutting the waste pieces forming the cut-away portions' from the sheet.

15. The method of producing from prepared roofing material shingle units, the.

waste, which comprises cutting a sheet of roofing material at intervals along lines to give *the unit the required contour, but leaving the waste parts attached to the sheet, and, between each cut, severing the waste material from the sheet.

16.,The method of producing from p-repared roofing material shingle units, the

contour of which involves the production of contour of which involves the production of waste, which comprises cuttin a sheet of roofing material at intervals along lines to give the unitthe required contour," but leaving the'waste parts attached to the sheet,

removing the cut unit from the sheet and,

following each cut, severing the waste ma terial from the sheet.

In testimony whereof I afiix my signature.
